METHODS AND APPARATUS FOR IMPROVING SEARCH RETRIEVAL

Abstract:

The disclosed subject matter relates to a system and method for providing an extended search. The system generates a list of synonym groups based on previous engagements linking queries and products. With receipt of a user query, the system accesses synonyms to the search terms and incorporates them into the query of the product catalog in order to obtain a complete set of results. The creation of the synonym groups uses various approaches including sequence tagging and graph embedding to identify synonyms in the query and the item titles.
